This book is freely available online. Here are a few of the chapter topics:

Miniature Spy Planes: The Next Generation of Flying Robots
Toward Micromechanical Flyers
Design Challenges for Future Wireless Systems
Next-Generation Mobile Wireless Internet Technology
Service Architectures for Emerging Wireless Networks
Wireless Integrated Network Sensors
Reengineering the Paralyzed Nervous Systems
Merging Living Cells and Microsystems Engineering

Here's a sample from a chapter mentioned above:

A typical miniature unmanned air vehicle has a quiet engine and is difficult to spot in the air. It can cruise the skies day or night in a wide range of weather conditions gathering information for law enforcement, traffic monitoring, air-pollution control, farming, fire spotting, power line inspection, search and rescue, and weather monitoring. Individuals will log on to a Web site and request image data for a specific region. This request will prompt teams of mini-UAVs to fly to the appropriate location, gather the requested data, and send the data to the customer over the Internet. The mini-UAVs doing the work will be all but invisible.
